TYPICAL APPLICATION
FEATURES DESCRIPTION
Single/Dual/Quad 220MHz, 1500V/µs Operational Amplifi ers
with Programmable Supply Current
The LT®1815/LT1816/LT1817 are low power, high speed, very high slew rate operational amplifi ers with excellent DC performance. The LT1815/LT1816/LT1817 feature higher bandwidth and slew rate, much lower input offset voltage and lower noise and distortion than other devices with comparable supply current. A programmable current option (LT1815 and LT1816A) allows power savings and fl exibility by operating at reduced supply current and speed. The circuit topology is a voltage feedback amplifi er with the slewing characteristics of a current feedback amplifi er.
The output drives a 100Ω load to ±3.8V with ±5V supplies. On a single 5V supply, the output swings from 1V to 4V with a 100Ω load connected to 2.5V. Harmonic distortion is –70dB for a 5MHz, 2VP-P output driving a 100Ω load in a gain of –1.
The LT1815/LT1816/LT1817 are manufactured on Linear Technology’s advanced low voltage complementary bipolar process and are available in a variety of TSOT-23, SO, MSOP, SSOP and leadless DFN packages.

ELECTRICAL CHARACTERISTICS The l denotes the specifi cations which apply over the full operating temp-erature range, otherwise specifi cations are at TA = 25°C (Note 8). VS = 5V, OV; VCM = 2.5V, RL to 2.5V, unless otherwise noted. For the programmable current option (LT1815S6 or LT1816A), the ISET pin must be connected to V– through 75Ω or less, unless otherwise noted.
Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime.
Note 2: Differential inputs of ±6V are appropriate for transient operation only, such as during slewing. Large sustained differential inputs can cause excessive power dissipation and may damage the part.

Note 3: A heat sink may be required to keep the junction temperature below absolute maximum when the output is shorted indefi nitely.Note 4: Input offset voltage is pulse tested and is exclusive of warm-up drift.Note 5: Slew rate is measured between ±2V at the output with ±3V input for ±5V supplies and 2VP-P at the output with a 3VP-P input for single 5V supplies.Note 6: Full-power bandwidth is calculated from the slew rate: FPBW = SR/2πVP
Note 7: This parameter is not 100% tested.Note 8: The LT1815C/LT1816C/LT1817C are guaranteed to meet specifi ed performance from 0°C to 70°C and are designed, characterized and
expected to meet the extended temperature limits, but are not tested at –40°C and 85°C. The LT1815I/LT1816I/LT1817I are guaranteed to meet the extended temperature limits.Note 9: Thermal resistance (θJA) varies with the amount of PC board metal connected to the package. The specifi ed values are for short traces connected to the leads. If desired, the thermal resistance can be substantially reduced by connecting Pin 2 of the TSOT-23, Pin 4 of the SO-8 and MS8, Pin 5 of the MS10 or the underside metal of the DD package to a large metal area.Note 10: A resistor of 40k or less is required between the ISET and V– pins of the LT1815S6 and the LT1816AMS. See the Applications Information section for information on selecting a suitable resistor.

Layout and Passive Components
As with all high speed amplifi ers, the LT1815/LT1816/LT1817 require some attention to board layout. A ground plane is recommended and trace lengths should be mini-mized, especially on the negative input lead.
Low ESL/ESR bypass capacitors should be placed directly at the positive and negative supply (0.01μF ceramics are recommended). For high drive current applications, ad-ditional 1μF to 10μF tantalums should be added.
The parallel combination of the feedback resistor and gain setting resistor on the inverting input combine with the input capacitance to form a pole that can cause peaking or even oscillations. If feedback resistors greater than 1k are used, a parallel capacitor of value:
CF > RG • CIN/RF
should be used to cancel the input pole and optimize dy-namic performance. For applications where the DC noise gain is 1 and a large feedback resistor is used, CF should be greater than or equal to CIN. An example would be an I-to-V converter.
Input Considerations
The inputs of the LT1815/LT1816/LT1817 amplifi ers are connected to the base of an NPN and PNP bipolar transis-tor in parallel. The base currents are of opposite polarity and provide fi rst-order bias current cancellation. Due to variation in the matching of NPN and PNP beta, the polar-ity of the input bias current can be positive or negative. The offset current, however, does not depend on beta matching and is tightly controlled. Therefore, the use of balanced source resistance at each input is recommended for applications where DC accuracy must be maximized. For example, with a 100Ω source resistance at each input, the 800nA maximum offset current results in only 80μV of extra offset, while without balance the 8μA maximum input bias current could result in a 0.8mV offset contribution.
The inputs can withstand differential input voltages of up to 6V without damage and without needing clamping or series resistance for protection. This differential input voltage generates a large internal current (up to 80mA), which results in the high slew rate. In normal transient
APPLICATIONS INFORMATION
closed-loop operation, this does not increase power dis-sipation signifi cantly because of the low duty cycle of the transient inputs. Sustained differential inputs, however, will result in excessive power dissipation and therefore this device should not be used as a comparator.
Capacitive Loading
The LT1815/LT1816/LT1817 are optimized for high band-width and low distortion applications. They can drive a capacitive load of 10pF in a unity-gain confi guration and more with higher gain. When driving a larger capacitive load, a resistor of 10Ω to 50Ω should be connected be-tween the output and the capacitive load to avoid ringing or oscillation. The feedback should still be taken from the output so that the resistor will isolate the capacitive load to ensure stability.
Slew Rate
The slew rate of the LT1815/LT1816/LT1817 is propor-tional to the differential input voltage. Therefore, highest slew rates are seen in the lowest gain confi gurations. For example, a 5V output step in a gain of 10 has a 0.5V input step, whereas in unity gain there is a 5V input step. The LT1815/LT1816/LT1817 are tested for a slew rate in a gain of –1. Lower slew rates occur in higher gain confi gurations.
Programmable Supply Current(LT1815/LT1816A)
In order to operate the LT1815S6 or LT1816A at full speed (and full supply current), connect the ISET pin to the nega-tive supply through a resistance of 75Ω or less.
To adjust or program the supply current and speed of the LT1815S6 or LT1816A, connect an external resistor (RSET) between the ISET pin and the negative supply, as shown in Figure 1. The amplifi ers are fully functional with 0 ≤ RSET ≤ 40k. Figures 2 and 3 show how the gain bandwidth and supply current vary with the value of the programming resistor RSET. In addition, the Electrical Characteristics sec-tion of the data sheet specifi es maximum supply current and offset voltage, as well as minimum gain bandwidth and output current at the maximum RSET value of 40k.

APPLICATIONS INFORMATION
Power Dissipation
The LT1815/LT1816/LT1817 combine high speed and large output drive in small packages. It is possible to exceed the maximum junction temperature specifi cation (150°C) under certain conditions. Maximum junction temperature (TJ) is calculated from the ambient temperature (TA), power dissipation per amplifi er (PD) and number of amplifi ers (n) as follows:
TJ = TA + (n • PD • θJA)
Power dissipation is composed of two parts. The fi rst is due to the quiescent supply current and the second is due to on-chip dissipation caused by the load current. The worst-case load induced power occurs when the output voltage is at one-half of either supply voltage (or the maximum swing if less than one-half the supply voltage). Therefore, PDMAX is:
PDMAX = (V+ – V–) • (ISMAX) + (V+/2)2/RL or
PDMAX = (V+ – V–) • (ISMAX) + (V+ – VOMAX) • (VOMAX/RL)
Example: LT1816IS8 at 85°C, VS = ±5V, RL=100Ω
PDMAX = (10V) • (11.5mA) + (2.5V)2/100Ω = 178mW
TJMAX = 85°C + (2 • 178mW) • (150°C/W) = 138°C
Circuit Operation
The LT1815/LT1816/LT1817 circuit topology is a true volt-age feedback amplifi er that has the slewing behavior of a current feedback amplifi er. The operation of the circuit can be understood by referring to the Simplifi ed Schematic. Complementary NPN and PNP emitter followers buffer the inputs and drive an internal resistor. The input volt-age appears across the resistor, generating current that is mirrored into the high impedance node.
Complementary followers form an output stage that buf-fers the gain node from the load. The input resistor, input stage transconductance and the capacitor on the high impedance node determine the bandwidth. The slew rate is determined by the current available to charge the gain node capacitance. This current is the differential input voltage divided by R1, so the slew rate is proportional to the input step. Highest slew rates are therefore seen in the lowest gain confi gurations.
